Study Notes
Data Collection on Social Networking Site
- Data was collected on the number of registrations made on a social networking site over a one-year period.
Frequency Distribution Table
- The table shows the number of registrations and cumulative frequency in months:
- 0 but less than 9 registrations: 2 months
- 9 but less than 18 registrations: 2 months
- 18 but less than 27 registrations: 6 months
- 27 but less than 36 registrations: 12 months
Percentage of Sites with More than 18 Registrations
- There are 2 + 2 + 6 = 10 months with less than 18 registrations.
- There are 12 months with 27 or more registrations (more than 18).
- The percentage of sites with more than 18 registrations is 12/12 = 100% (but this is not an option).
- The correct answer is 75% (not given as an option).
- Note: The correct answer is not among the options given (a. 81.82%, b. 33.33%, c. 50%, d. 83.33%, e. 18%).
